GLU E-SPREADING MACHINE.

SPECIFICATION forming part of Letters Patent No. 627,567, dated une 27, 1899. Application iiled August 30, 1898. lSerial No.689J884. (No model.)

T all whom it may concern:

Be it known that I, WILLIAM C. BosENBURY, a citizen of the United States of America, and a resident of Richmond, in the' county of Wayne and State oflndiana, vhave invented certain new and usefullmp'rovements in Glue- Spreading Machines,`0f which uthe vfollowing is a specification.l 'A Y,

My invention relates to an improved machine for spreading glue-that is, a machine to spread glue upon vsurfaces of boards when forming veneered or laminated surfaces.

One object of my invention is the provision of a machine for the purpose stated and of the character named which is adapted to spread glue upon surfaces of any thickness or width, which will spread glue upon the top as well as the bottom surface, which can be operated by any manner of power, and which will do its work in an efficient and thorough manner.

Another object of my invention is the provision of a glue-spreading machine which will operate upon straight or curved surfaces,

which is adjustable in every particular, and;

which .is the embodiment 'forfa machine of this kind of simplicity and durability, and also which is ineXpensive'to manufacture and will also operate and perform its functions in a perfect and thorough manner. v -Y To attain the desired objects, the invention consists of a glue-spreading machine embodyf ing novel features of construction and com bination of parts, substantially as disclosed herein.

Figure 1 represents a front elevation of my improved glue-spreadingmachine, the gluei pot being in section. Fig. 2 is a side elevation thereof, showing1 the normal position of the glue-spreading mechanism, the glue-pot also being in section; and Fig. 3 is a similar view with the glue-spreading mechanism in the position it assumes when ready for use.

In the drawings the numeral 1 designates the base, having mounted thereon the standards 2,the braces 3,and the glue-pot support 4.' Secured upon the face of the standards are the guides 5,'between which is mounted the movable frame 6, upon whose rearedges are the rack-teeth 7, which are operated upon or engaged by the gear-wheels 8, mounted upon the shaft 9, which is journaled in the standards, said shaft being operated upon by the hand-wheel to raise or lower the movable frame 6. Journaled in this frame 6, near the top thereof,is the shaft 11,having thesprocketwheel 12, over and around which passes the sprocket-chain 13, said sprocket and chain being revolved by means of the shaft 14, journaled in the bearings on the braces 3 and carrying thewloose and fastpulleys 16 and 16X, which are operated upon by a band from any kind of power or driving mechanism, and secured upon the end ofthe said shaft is a sprocket-wheel 17, which is adapted to revolve the sprocket 12, and' chain 13 to revolve the shaft 11. Upon thejotherend of the shaft 11 is the bevel gear-wheel 18,which meshes with the bevelgear-wheel 19 upon the end of the vertical shaft 20, which is j our-v naled in the bearings 21, and secured upon the lower portion of said shaft with their faces toward each other are the bevel gearwheels 22 and 22X,'the top onefof which is slidably mounted upon the portion 20 of the vertical shaft 20, and both of said gear-wheels are adapted to engage thebevel'gear-wheels 23 and 23X, mounted upon theends o f the rollers 24 and 24X. y

The roller 24is mounted in the slidingframe 25, which is held in the frame 6 by means 0f the guide-strips 26 and through which frame at the top are the adjusting-screws 27, whichl are j ournaled in the braces 28,and upon the upperends of the said adj usti'nglscrews'A are'secured the bevel gear-wheels 28X,'wh'oseteeth mesh with the bevel gear-wheels 29, secured upon the shaft 30, which is journaled in the bearings 31, secured in the upper portion of the frame 6, said shaft having one endsquared for the reception of a handle, which is revolved to raise the sliding frame to spread the rollers apart so as to receive a thin or a thick piece of board. Secured to this sliding frame j ust in front of the top roller is the glue-feeding receptacle 32, having openings in its bottom so as to feed the glue4 to the topY roller while the machine is in operation, and also secured to the top roller at its endsare the arms 33, and having secured therein the curved arm 34, having resting thereon the other oppositely-arranged curved arm 3.5, whose ends are forced downward by means of the set-screws 36, mounted in the braces or arms 37, which are secured to the upper parts of the sliding l'OO frames 25, the whole forming a tension device for the rollers. The roller Six is journaled in vertical bearings 3S, which are mounted between the end of the frame and the foot 3f) of said frame.

Resting upon the glue-tank support -t is the tank 40, which is adapted to contain the water, and suspended in said tank is the glue-pot 4l, into which the frame G is adapted to be placed or over which it is adapted to be operated. The frame 6 is so constructed that when raised to its highest position for use the lower rollers lowest point on its surface will be immersed in the glue.

I would state here that the rollers surface may be covered with felt or carpet or in fact with any material that would operate as desired.

From this description, taken in connection with the drawings, the operation of the machine is readily understood, but briefly stated is as follows: In Fig. l the frame is lowered, being out of use, but when it is desired to use the lnachine the movable frame 6 is raised by means of the rack-and-sprocket mechanism to the position shown in Fig. 3, the rollers being adjusted to the thickness of the board, the spreading mechanism is set in action by means of the vertical shaft and the horizontal shafts which carry the bevel gear-wheels and the fast and loose pulleys which are connected to the driving mechanism, and it will be seen that the machine may be stopped or set in action by shifting the band from the driving power from the loose to the fast pulley, or vice versa. It will thus be seen that when the machine is not in use both the gluespreading rollers and the glue-tank carried by the upper roller are fullyimmersed iu the main glue-tank, which being kept heated prevents the glue on the rollers and in the small tank from hardening, and also that the small tank is filled in preparation for use. /Vhen the machine is to be used, the frame carrying the two rollers is lifted to raise the upper rollerentirely out of the glue and permit the passage of material between the rollers, while the lower roller-still remains su iiiciently within the tank to receive glue therefrom and apply it to the lower surface of the material, while the upper roller applies the glue to the upper surface thereof as the material is passed between the rollers.

It is evident that I provide a glue-spreading machine which is adjustable to accommodate various thicknesses of board, which is easily and quickly set in motion or stopped, and which is simple and durable, as well as extremely cheap and practical.
